The singular terms "one" and "the" may also include plural forms.

[0023] In modern intelligent living environments, in order to achieve automatic room temperature adjustment, it is necessary to accurately understand the number of people in the room. This is because the number of people in the room directly affects the heat load of the room, which in turn has a direct impact on the load of the refrigeration equipment. In order to achieve energy saving and provide a comfortable living environment, it is particularly important to accurately detect and calculate the number of people in the room.

[0024] In an example of an application scenario of the present invention, an air-conditioning system includes at least one millimeter-wave radar, wherein the millimeter-wave radar is arranged at an entrance or exit of a room.

[0025] Embodiment 1:

[0026] See attached Figure 1 , Figure 1 FIG. 1 is a flow chart showing the main steps of a method for controlling the temperature of an air conditioning system according to an embodiment of the present invention. Figure 1 As shown, the method for controlling the temperature of the air-conditioning system in the embodiment of the present invention mainly includes the following steps S10 to S30.

[0027] Step S10: Acquire first radar data of the millimeter wave radar.

[0028] In this embodiment, the first radar data is scanned data about the entry and exit of people.

[0029] In one embodiment, the millimeter wave radar is a sensor based on electromagnetic waves, and its operating frequency is generally in the range of 30-300GHz. Compared with conventional cameras or infrared sensors, millimeter wave radar has many advantages. First, it can penetrate non-metallic and non-conductive materials, such as clothing and walls, to achieve a wider detection range. Secondly, it does not capture specific image information, but only captures the motion and position information of the target object. This feature enables it to efficiently provide the required data in the detection and estimation of the number of people, and it is not easy to damage the privacy of individuals. Therefore, by using millimeter wave radar, compared with traditional cameras, it can avoid possible privacy leakage problems and provide users with a safe and worry-free living and working environment.

[0030] Millimeter-wave radar technology also has many other advantages, such as strong anti-interference ability to environmental factors (such as light, smoke, etc.), wide adaptability, and the ability to work stably in a variety of environments.

[0031] Considering that the entrance and exit of a room are the main channels for people to enter and exit, in this embodiment, the millimeter wave radar is set at the entrance and exit of the room. Setting it at this position can ensure effective detection of everyone entering and leaving the room. In addition, the location of the entrance and exit is relatively fixed and easy to install equipment, which is more conducive to the stable operation and long-term operation of the radar.

[0032] In step S10, the system obtains first radar data through the millimeter wave radar installed at the entrance and exit of the room. These data can effectively represent the movement and position of the human body in the room based on the reflection and scattering characteristics of the human body to millimeter waves. The acquisition of these data is to lay the foundation for the subsequent number analysis step, so as to more accurately set the working parameters of the refrigeration equipment, thereby creating a more comfortable environment for the people in the room.

[0033] In this embodiment, after step S10, there are steps S101-S102 for further strengthening privacy protection.

[0034] Step S101: After acquiring the first radar data, encrypt the first radar data.

[0035] In this embodiment, the encryption process is to encrypt the first radar data using a highly secure encryption algorithm.

[0036] In one implementation, although millimeter-wave radar itself is a privacy-friendly sensor technology, there are still possible security risks in the process of data collection, transmission and processing. In order to ensure the integrity and confidentiality of the data, timely data encryption is particularly critical.

[0037] In this embodiment, when the millimeter wave radar captures the first radar data, the data will first be sent to the embedded secure processor (ESP). The millimeter wave radar is directly connected to the embedded secure processor, and the main task of the embedded secure processor is to start the encryption process at the moment of receiving the radar data to ensure that the data has been properly encrypted before any other processing. This not only ensures the security of the data, but also ensures the integrity and reliability of the entire processing chain.

[0038] In this embodiment, once the millimeter wave radar captures relevant first radar data, the data will be sent to the embedded security processor in real time.

[0039] The embedded security processor has a dedicated security module inside, which is responsible for the storage and management of keys. During the device manufacturing or deployment stage, these keys will be pre-loaded into the embedded security processor and locked to ensure that they will not be leaked or tampered with even in the event of an attack.

[0040] After receiving the data from the radar, the embedded security processor will immediately start the encryption process. Using the pre-stored encryption key, the embedded security processor can choose AES or RSA encryption algorithm to process the data. The following is a brief description of the two encryption methods:

[0041] AES: A symmetric encryption algorithm that requires the same key to encrypt and decrypt data. It provides fast and secure data conversion capabilities and is particularly suitable for systems that require a lot of real-time processing.

[0042] RSA: An asymmetric encryption algorithm based on mathematical principles that requires a pair of public and private keys to operate. In this system, the public key is used to encrypt radar data, while the private key is used in the subsequent decryption process.

[0043] In this implementation, the successfully encrypted data is not immediately transmitted or processed. To ensure its integrity and security, the data is first securely stored in a dedicated storage area of ​​the embedded security processor. This storage area has a hardware-level protection mechanism that can effectively defend against various attacks, both physical and electronic.

[0044] In summary, step S101 not only enhances the data security of the system, but also provides a safe and reliable data foundation for subsequent data processing and analysis.

[0045] Step S102: The first radar data can be decrypted only when the first radar data is in a protected memory area.

[0046] In this embodiment, the protected memory area is a secure execution environment (SEE).

[0047] In one embodiment, the protected memory area provides an isolated, strictly protected area for data, where all operations (such as reading, writing, processing, etc.) are completed in this closed environment, completely isolated from the rest of the system.

[0048] In this embodiment, not all programs or processes can be executed in the protected memory area or access the data therein. Only processes or applications with specific permissions can operate in the SEE. This permission management is intended to ensure that only processes that have been verified and deemed to be trusted can perform decryption operations.

[0049] When data needs to be decrypted, it is first moved from its original storage location to a protected memory area. In the protected memory area, the private key or symmetric key can be safely used for decryption operations, ensuring that the data will not be illegally accessed or leaked during the decryption process.

[0050] In protected memory areas, key management policies are usually stricter. Keys are not stored in plain text, but are securely stored and processed by specific hardware modules, such as Hardware Security Modules (HSMs).

[0051] In summary, step S102 emphasizes that decryption operations can only be performed in a protected SEE, ensuring that sensitive data is always highly protected even in the most adverse environment. This design concept demonstrates a deep commitment to user privacy and data security, ensuring that data is always in a controlled and protected state during processing.

[0052] Step S20: Obtain a first total number of people in the room based on the first radar data.

[0053] In one implementation, the first total number of people in the room is obtained through a series of methods and skills such as target detection, feature extraction, and headcount, as follows:

[0054] Object detection is usually presented as a two-dimensional or three-dimensional echo image, which will be further applied to advanced image processing and computer vision algorithms to identify and highlight moving or stationary objects in the room, that is, the presence of people.

[0055] Once each target is accurately marked, the system begins to extract the unique features of each target, such as its size, shape, and movement trajectory. These features provide the basis for subsequent classification and identification. Next, the system counts the number of people based on these features. Whenever a target is detected that meets the characteristics of a person, the number of people counted will increase accordingly.

[0056] However, to ensure statistical accuracy, it is necessary not only to rely on these features, but also to have a verification mechanism. For example, if the movement trajectory or speed of a target does not match the behavior of a normal person, the system may evaluate the target again or ignore it directly.

[0057] As people enter and leave the room, the radar data is continuously updated, and the system will synchronously analyze the new data to ensure that the headcount is always consistent with the actual situation. To further improve accuracy, this step can also be combined with deep learning, machine learning or other AI technologies to train and optimize the model to make recognition more accurate.

[0058] In this embodiment, obtaining the first total number of people in the room is achieved through steps S201-S203. Figure 2 The details are as follows:

[0059] Step S201: injecting random noise into the first radar data to obtain second radar data.

[0060] In this embodiment, the second radar data is data into which noise has been injected.

[0061] In one embodiment, in order to further enhance privacy protection, a unique obfuscation strategy is implemented for the first radar data. In this embodiment, the obfuscation strategy is implemented by injecting a specific amount of random noise into the first radar data. This noise injection strategy is intended to ensure that specific details of the original radar data, such as the precise location or morphological characteristics of an individual, become more difficult to identify, thereby achieving privacy protection.

[0062] Random noise is usually generated using random number generation algorithms. These algorithms are designed to be both efficient and secure, ensuring that the generated noise follows a certain statistical distribution, such as Gaussian or uniform, and the parameters of these distributions, such as the mean and standard deviation, can be fine-tuned as needed to control the intensity and nature of the noise.

[0063] The injection of noise is not overly arbitrary. It needs to be adjusted to a certain extent to ensure that while blurring the radar data, it does not cause excessive interference to the subsequent detection of people. Too much noise may make the radar data difficult to interpret, while too little noise cannot effectively protect privacy. The specific injection is related to the resolution accuracy of the millimeter wave radar. If the resolution accuracy is high, the noise injection will be increased, and if the resolution accuracy is low, the noise injection will be reduced.

[0064] In this embodiment, the key to the fuzzification process is to find a balance point: to blur the specific details of the data to the maximum extent without affecting the accuracy of the number of people detected. Therefore, in order to achieve the balance requirement, this step will be combined with some advanced digital signal processing technologies. Preferably, in this embodiment, adaptive filtering and spectrum analysis are used to adjust and optimize the noise injection process.

[0065] In summary, step S201 not only provides an additional layer of privacy protection for radar data, but also ensures the reliability and accuracy of data processing and analysis.

[0066] Step S202: Obtain a first total number of people in the room based on the second radar data.

[0067] In this embodiment, the technical means for obtaining the first total number of people is similar to that in step S20 and will not be described in detail here.

[0068] Step S203: After obtaining the second radar data, discard the first radar data.

[0069] In one embodiment, this method is to ensure the complete removal of the first radar data. This process is not only to save storage space, but more importantly, it is out of privacy considerations. Although the first radar data has been encrypted, in order to ensure that the data will not be improperly accessed or used, the best practice is to completely delete it.

[0070] In this embodiment, considering the integrity of the data processing flow, discarding the first radar data requires some verification steps. This includes ensuring that the data has been correctly converted into the second radar data. Once these verification steps are completed, the data deletion operation can begin.

[0071] In this embodiment, it is ensured that after the second radar data is obtained, the first radar data is completely and securely deleted, thereby protecting user privacy to the greatest extent.

[0072] Step S30: Setting the temperature in the room based on the first total number of people.

[0073] In this embodiment, setting the temperature in the room is accomplished by sending instructions to the air conditioning system.

[0074] In one embodiment, temperature regulation aims to provide the most comfortable living and working environment possible while minimizing energy consumption. For air conditioning equipment, the number of people in a room is a key factor affecting the temperature. A large number of people in a room may cause the temperature to rise faster because each person releases a certain amount of heat.

[0075] By using millimeter-wave radar to detect the total number of people in a room and adjust the temperature accordingly, it can not only provide more personalized comfort, but also achieve more precise energy management. For example, if there is no one or a small number of people in the room, the air conditioner can run at a relatively low power, thus saving energy; when the number of people in the room increases, the air conditioner needs to increase the power to ensure that the room temperature remains within a comfortable range.

[0076] In order to accurately adjust the working state of the air conditioner according to the number of people, different thresholds are set. These thresholds are determined based on statistical data, research on human heat release and the performance of air conditioning equipment, so as to ensure that the best temperature setting can be obtained under different number of people.

[0077] In this embodiment, the temperature in the room is dynamically set through steps S301-S304.

[0078] Step S301: Obtain a preset first threshold and a second threshold, wherein the second threshold is greater than the first threshold.

[0079] In this embodiment, the two thresholds are introduced to accurately divide different ranges of people in the intelligent temperature control system, and then adjust the indoor temperature to an appropriate level.

[0080] Then compare the relationship between the first total number of people and the first threshold and the second threshold

[0081] Step S302: If the first total number of people is less than or equal to the first threshold, the room temperature is set to a first preset temperature.

[0082] In one embodiment, when the total number of people in the room is less than or equal to the first threshold, the system determines that the number of people at this time is within a normal or small range. In this case, adjusting the room temperature to the first preset temperature is intended to provide a suitable temperature environment for the number of people present. Once it is determined that the temperature needs to be set to the first preset temperature, the control system will send a corresponding signal through the interface with the air conditioning or heating system to instruct it to adjust to the required temperature.

[0083] Here is an example. When the first threshold is 20 people and the first preset temperature is 26 degrees Celsius, if the first total number of people is 16, the room temperature is set to 26 degrees Celsius.

[0084] Step S303: If the first total number of people is greater than the first threshold and less than or equal to the second threshold, the room temperature is set to the second preset temperature.

[0085] In one embodiment, when the total number of people in the room exceeds the first threshold but does not exceed the second threshold, the system determines that the current number of people has increased but has not yet reached a peak. This means that the heat generated in the room will increase slightly, which may affect people's comfort. In order to make appropriate temperature adjustments, the control system sets the temperature to a second preset temperature. The interface between the control system and the air conditioning or heating system will send a signal to ensure that the air conditioning or heating system is adjusted to this predetermined temperature.

[0086] Taking the actual situation as an example, if the first threshold is set to 20 people, the second threshold is set to 40 people, and the second preset temperature is 25 degrees Celsius, then when the total number of people in the room is 30, the system will recognize this change and adjust the room temperature to 25 degrees Celsius.

[0087] Step S304: if the first total number of people is greater than the second threshold, the room temperature is set to a third preset temperature, wherein the first preset temperature, the second preset temperature and the third preset temperature are sequentially decreased.

[0088] In one embodiment, when the total number of people in the room exceeds the second threshold, it indicates that the number of people in the room has reached a peak state. In this case, the heat released in the room will increase significantly, causing the indoor temperature to rise, which may make people feel uncomfortable. In order to maintain the comfort level in the room, the control system sets the temperature to a third preset temperature. The control system communicates with the interface of the air conditioning or heating system and sends a signal to instruct it to adjust to the third preset temperature.

[0089] For further explanation, assume that the second threshold is 40 people and the third preset temperature is set to 24 degrees Celsius. At this time, if the total number of people detected in the room is 45, the system will respond quickly and instruct the air conditioning or heating system to adjust the room temperature to 24 degrees Celsius.

[0090] Embodiment 2:

[0091] Most of the technologies in this embodiment are the same as those in Embodiment 1, except that multiple millimeter wave radars are used to identify people in this embodiment. Other than that, the remaining technologies are the same as those in Embodiment 1, and will not be described in detail here.

[0092] In modern architecture and room design, in order to optimize space layout and flow, improve safety or meet specific functional requirements, some rooms are designed with two one-way passages, one for entrance only and the other for exit only. This design is intended to regulate the flow of people and avoid crowds and chaos, especially during peak hours or in special situations, such as emergency evacuation.

[0093] For a room with such a specific structure, a traditional single radar monitoring system may have difficulty in accurately counting the total number of people in the room because it may miss some people entering or leaving the room through a one-way passage. To solve this problem, this embodiment uses two millimeter-wave radars, namely a first millimeter-wave radar and a second millimeter-wave radar.

[0094] The first millimeter-wave radar is responsible for monitoring the first one-way channel, and the data collected is called the third radar data, while the second millimeter-wave radar is responsible for monitoring the second one-way channel, and the data collected is called the fourth radar data. This dual radar design ensures that everyone entering or leaving from the two one-way channels is accurately detected and recorded.

[0095] Step S204: Obtaining a first total number of people in the room based on the third radar data and the fourth radar data

[0096] In this embodiment, the calculation method here is similar to that in step S20 and will not be repeated here.
